Another Dumb Joke – Are these plates clean…

Jim went to visit his 90 year old grandfather and while eating breakfast he notices his plate isn’t clean. So he asks, “Granpa, are these plates clean?” His grandfather replies, “Those plates are as clean as cold water can get them.”

That afternoon, while eating the hamburgers his grandfather made for lunch, he noticed black specks around the edge of his plate so again he asked, “Granpa are you sure these plates are clean?” Without looking up from his burger, the grandfather says, “I told you they’re as clean as cold water can get them, now don’t ask me about it anymore.”

Later that day, Jim decided to take his grandfather out to dinner. As they were leaving the house, his grandfather’s dog started to growl and wouldn’t let them pass.
